Abstract

Nanoparticles of TiO2 have been the main semiconductor applied in Dye-sensitized solar cells (DSSCs). In this work, solar cells were developed from the electrophoretic deposition of anatase titanium dioxide (TiO2) films on conductive glasses. The electrophoretic deposition was perfomed with a constant voltage of 80V for 2 minutes and, after drying, the films were sintered at three different temperatures: 450 °C, 550 °C and 600 °C. In the assembly of the cells, the titanium dioxide films were sensitized by Ruthenizer 535-bisTBA dye (N719) and an electrolyte containing the iodide / tri-iodide redox pair and a commercial transparent platinum counter electrode were used. TiO2 films were characterized by scanning electron microscopy, dispersive energy spectroscopy and X-ray diffraction and photo-electrochemical techniques. The energy conversion rates were 0.2646% for the sintered film at 450 °C, 0.1209% for the sintered film at 550 °C and 0.1137% for the film sintered at 600 °C. Keywords: Dye-sensitized solar cells. Electrophoresis. Titanium dioxide. Film. Mesoporous. Photoanode.

电泳沉积氧化钛在染料敏化太阳能电池光电极上的性能评价

二氧化钛纳米颗粒是染料敏化太阳能电池(DSSCs)中应用的主要半导体材料。在这项工作中，太阳能电池是由锐钛矿型二氧化钛(TiO2)薄膜在导电玻璃上的电泳沉积而成的。电泳在80V恒定电压下沉积2分钟，干燥后在450℃、550℃和600℃三种不同温度下烧结膜。在电池的组装中，二氧化钛薄膜用Ruthenizer 535-bisTBA染料(N719)敏化，并使用含有碘化物/三碘化物氧化还原对的电解质和商业透明铂对电极。采用扫描电镜、色散能谱、x射线衍射和光电化学技术对TiO2薄膜进行了表征。450℃时烧结膜的能量转化率为0.2646%，550℃时烧结膜的能量转化率为0.1209%，600℃时烧结膜的能量转化率为0.1137%。关键词:染料敏化太阳能电池;电泳。二氧化钛。电影。介孔。光电阳极。
